BEARING FOR DEAD-SPINDLE SLEEVES.

SPECIFICATION forming part of Letters Patent No. 560,393, dated May 19, 1896. Application filed July 29, 1895- Serial No.55'7,416. (No model.)

To aZZ whom it may concern.-

Be it known that we, JOSEPH W. CoLLINs and HENRY COLLINS, of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Bearings for Dead-Spindle Sleeves; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to that class of spindle-bearings intended to be used with dead-, spindles or stationary spindles, on which a loose tube or sleeve revolves and carries the bobbin. It is fully explained and illustrated in this specification and the accompanying drawings.

Figure 1 represents an elevation of a spindle, supporting-rail, lifting-rail, and sleeve for the bobbin. Fig. 2 is a vertical section taken down through the center of the spindle and rails. Fig. 3 is a horizontal section taken on line w as, Fig. 2.

The construction of the improvement is as follows: A spindle Bis held stationary in a railAby means of a screw-thread onits lower end, which is fitted in the rail and serves to set it up or down by turning the spindle around, and a set-screw a inserted in the front of the rail holds it from turning when set. A sleeve 0 is held on the spindle B, so

as to revolve freely, and is provided with a collar 17, on which the bobbin rests, with two steady pins or flanges s s to enter the lower end of the spool and insure its turning with the collar 6. Another collar J is made lower down on the sleeve, and between the collars awhirl y is formed to receive thebelt or tape that drives the sleeve and bobbin. A collar or washerl),which fits loosely on the spindle B, rests on the lifting-rail H, and has an annular recess 92 made in its upper side to receive a washer o, of felt or other absorbent material, and a hole e is made through the inner wall of the recess 42 to let the oil pass through to the spindle. A small collar 9 is placed loosely on the top of this inner wall, having its inner upper corner cut out to about a quarter of a circle in cross-section, and a like collar g is placed on the top of collar g, only in a reversed position, so that the two grooved corners come together and form a recess nearly circular in cross-section, in which a row of hard steel balls 2' z are placed. The balls are large enough in diameter to hold the collars g and g a small distance apart at their outer corners. A vertical flange 0 extends down from the under side of the flange J to serve as a screen or curtain to keep the dust and lint out of the ball-chamber. The collars D, g, and g are all perfectlyfree to turn with the sleeve, singly or together, or to remain still, as may induce the least friction. The oil is put in the recess on the felt and works through the hole e to the spindle,which receives all the oil it needs as the lifting-rail H carries the sleeve up and down on it. By this arrangement of the parts no oil can be thrown off by centrifugal force or dust or lint enter the chamber and clog the valves.

Having thus described our improvement, we claim as our invention and desire to secure by Letters Patent- In a bearing for a sleeve of a stationary spindle, a collar recessed in its upper side and having an absorbent Washer therein and an opening through to the surface of the spindle, two small collars having their adjacent inner corners removed to form a chamber supported on the inner flange forming said recess, a circle of balls in said chamber, in combination with a stationary spindle, a loose sleeve held thereon and having horizontal flanges to form a whirl, and a vertical flange extending down around thecollars holding the balls, and supporting-rails for said spindle and sleeve, substantially as described.
